Configurable Multi-Row DuPont Contact Jig

Overview

This is a fully customizable contact jig designed for DuPont-style connectors, perfect for hobbyists, makers, and electronics enthusiasts. Whether you need a 1x6, 2x8, or any other pin layout, this jig adapts to your project with ease. It’s a versatile tool for crimping, inserting, or testing DuPont pins and cables, featuring a random mix of contact slots and needle cylinders for unique wiring setups.

Key Features

• Configurable Layout: Use the included OpenSCAD file to set any number of rows and pins per row—tailor it to your exact needs!
• Robust Design: Thick base (12 mm), large chamfers on slots (2 mm), and tall needles (25 mm) ensure durability and ease of use.

How to Use It

1. Customize & Print: Open the OpenSCAD file and adjust num_rows, pins_per_row, active_pins, and active_needles to your desired layout. Export and print with a strong filament (e.g., PLA, PETG) at 0.2 mm layer height—no supports needed.
2. Insert DuPont Pins: The top side is the insertion side. Push DuPont pins into the chamfered slots as defined by your configuration. Pin holes align with the jig’s needles.
3. Crimp Cables: Attach wires to the DuPont pins. Needle cylinders (placed per your design) can guide or test connections.
4. Remove Cables: Pull the cables out from the insertion side as needed.

Customization

• OpenSCAD Power: Modify row count, pin count, and slot/needle patterns in the script. Adjust dimensions or other parameters to fit your project.

Applications

• Prototyping custom DuPont connectors for Arduino, Raspberry Pi, or any electronics project.
• Testing pin configurations with configurable needle placements.
• Managing complex or unique wiring setups with ease.
